What to consider before buying a string trimmer line?

The process of choosing string for your weed eater should be considered carefully. If you use the wrong product, it could force you to stop and reload all the time.

Here are some considerations you should notice before buying a trimmer line.

1. Is it easily compatible?

The first thing you should pay attention to is compatibility because the process will be corrupted if you cannot use the line on your model.

Most manufacturers will state the kind of trimmer line that their products use and also the style and dimensions.

Also, the trimmer line manufacturers will clearly point out the string trimmer types and models that their lines are meant for on your packaging. So your task is simply taking some time to read the description to ensure you acquire a compatible one.

2. What shape to choose?

Since there are so many styles of trimmer lines in the market, it is of importance to know that they come in different styles. Knowing the trimmer line styles will help you pick the right line.

Multi-Sided Trimmer Line

multi sided trimmer line

If your house has a big yard covered with thick weeds you should consider using a multi-sided line. It is also a wise choice for commercial purposes. As the name suggests, it comes with multiple sides with the pentagon, star, and square being the most typical shapes.

Round Trimmer Line

round trimmer line

The Round trimmer line is the most in favor of the five different styles. People apply it with the purpose of getting rid of weeds around a residential area and trimming grass edges.

Twisted Trimmer Line

twisted trimmer line

A twisted style line is appropriate with gardens that have a lot of thick and heavy weeds. It is the most appropriate trimmer line for professional trimming purposes because it does not break when you hit trees or even concrete.

Square Trimmer Line

squared trimmer line

People often make use of square trimmer lines with the idea of cutting thick weeds. This line type is equipped with various sides that facilitates the weed eater to eliminate all the grass or weeds standing in its path.

Serrated Trimmer Line

Serrated Trimmer Line

The serrated line is applied when you have a lot of weeds around your property or if you clip yards at a professional level. This line is ideal for use when you have plants that are thicker than normal and a large area to cover within a short time.

3. Is it durable?

You should buy a trimmer line for long-term use in order to avoid replacing it frequently.

There is a wide range of things that determine durability, but the key ones are the material used to make the line and how it is made.

Normally, titanium lines are better in this aspect than nylon ones, but some manufacturers will also use a different type of nylon material to make their lines last longer.

4. Is it resistant to welding?

We have already known that welding just happens when the trimmer string overheats then stick together on the spool. It is created by operating the trimmer at high speed while for an extended time. The added friction causes inordinate heat buildup, which eventually causes it to stick together.

While the materials used to form trimmer strings are all reasonably weld resistant, some types of string have a higher level of resistance than others.

I advised you to choose the shaped line for a better experience. Because the shaped line is more weld-resistant than the round one because of the increased surface area, given the same material.

The round string has the least amount of surface space, enabling heat to increase quickly.

5. And the line diameter?

Not all sizes fit all trimmers, so be sure to read the manufacturer’s directions before buying string for your trimmer.

A light-duty trimmer string of 0.065 to 0.085-inch diameter is appropriate for narrow and medium yards with few weeds.

A medium-duty trimmer string of 0.085 to 0.110-inch diameter is a wise choice for larger yards and yards with thick grass and more weeds.

Heavy-duty string greater than 0.110-inch in diameter can be used for large properties with heavy weeds.

Are all trimmer lines the same?

Absolutely not. There are diverse brands on the market: fuel-powered, electric, and cordless models, and each has its distinct trimmer head.

Many of these heads have many things in common with nature from one brand to the next that standard weed wacker line can be used from one make and model to the other.

However, you need to focus on how the line is used, the shape, and the diameter when making a purchase.

How to choose a trimmer line suitable for your work?

In order to acquire an appropriate trimmer line, you need to read the manual to obtain information about its applied environment and its adaptability.

Also, take into account the noise problem you will cause when using. If you live where there are noise restrictions, consider buying a smaller, or shaped line to make sure you do not break the regulations.

How to install a string trimmer line?

The installation will highly depend on the line style you have and also your trimmer head type. Here the general steps that you can apply with most of the trimmer lines in the market.

Step 1: Remove spool

  • Turn off your trimmer
  • Disconnect it from the power source.
  • Locate and push the release button to remove the spool (or follow the manual of your trimmer to remove it)

Step 2: Throw away the old line

  • Take out all the remaining old lines. Any left might cause damage and failure of usage.

Step 3: Install the new line

  • You can start by installing a 9-foot trimmer line (the most common length for trimmers).
  • If you have a double-line trimmer, install 2 9-foot lines.
  • On the spool, wind the new lines following the directions of the arrows, until a 6-inch line has remained

Step 4: Test new line

  • To check whether your new line is working properly, switch it on and see how it cuts.
  • If any snag appears, remove the spool and start winding the line again.

FAQs about Sring Trimmer Lines

1. Is trimmer line biodegradable?

The answer is a big “NO” unless your trimmer line comes from environment-friendly brands. In contrast, mower strings are single-use plastic – a source of pollution that few people notice.

During operation, trimmer strings will scatter into small plastic pieces. And these pieces will mix with your plants and soil. Unfortunately, most mower lines are made from persistent plastic which can take thousands of years to decompose completely.

If your concern is the environment, choose a trimmer line with high durability. It helps minimize the number of times they break and release plastic into the environment. A string from a biodegradable brand sounds nice, too.

2. Does trimmer line size matter?

Choosing the line size – or line diameter – is essential. It significantly affects the productivity and durability of the line. If you use the wrong trimmer string size, your job will be challenging to complete.

Which mower line diameter should you pick? Well, it will depend on the terrain, type of grass, and job requirements. Remember one rule: the more challenging the job, the thicker the line size.

If you’re a newcomer, read the manufacturer’s instructions carefully to find out what size your string is suitable for the job.

3. Does trimmer line shape matter?

The shape of the line does matter. That’s why it was invented.

Typically, there are four main types of string shapes: round, multi-sided, serrated, or twisted. As with line size, which line forms to choose is entirely up to your trimming needs. From round to twisted, the cutting efficiency of the trimmer line will increase, but the strength will decrease.

Therefore, the round structure is always the most preferred choice for home use. It can handle light jobs as grass trimming and offer great longevity. The string shape will be different when it comes to industrial purposes or taking heavy work. Strings with sharp edges that provide higher cutting capacity will be preferred.

4. Is a thicker trimmer line better?

There’s no one-size-fits-all answer for this concern. It all depends on the difficulty of the application.

Trimmer lines come in various sizes. Depending on the amount of work, the string diameter you need will be different. If you only plan to mow the lawn or do other light work, the small line size will give you quick, effortless cuts.

But you’ll need thicker lines for heavy lifting, like mowing dense bushes or tough weeds. However, trimmer line size also affects how much power you need to supply to the mower. The thicker the line is, the more power the head machine needs.

5. Is twist trimmer line better than round?

What is the end goal of your trimming job? Answering this question, you will find out what is your best mower line shape.

Round lines

Choose a round string if you only mow the lawn at home or for other residential uses. These string cuts are perfect for light and repetitive work.

The rounded construction also provides the ultimate durability, making the line last longer with less breakage. This standard cord is also very easy to replace in case of damage.

Twisted lines

If you’re looking for a product for commercial use or for clearing thick weeds, a twisted trimmer line comes to mind. They cut through hard surfaces and bushes with great ease. The cut is immaculate while the noise is minimized.

However, they will not be as popular as round-shape lines because of their price, durability, and convenience in use.

6. Why does the trimmer line keep breaking?

There are three leading causes for your continuous mower line breakage.

  • Firstly, you often put the trimmer line in contact with rocks, walls, fences, etc., while cutting.
  • Second, you’re using a trimmer line that doesn’t match the mower. Please check the trimmer’s requirements to choose the most compatible string!
  • Third, your lines have been used for too long, and it’s time for them to be replaced. It is normal wear and tear.
